Processing binary options in future exchange clearing

ABSTRACT

Systems and methods are disclosed for processing binary options (also referred to as digital options) in existing clearing systems, such as futures clearing systems. The binary option is treated, or processed, similar to standard options on a non-tradeable cash-settled underlying futures contract. A hypothetical instrument, referred to as a book instrument is created to facilitate clearing of the binary option. The book instrument has an expiration date after the expiration of the binary option, such as the day after the expiration of the binary option. For each binary option that expires in the money, a transaction is created for the book instrument future. The underlying book future has an assigned price that is a fixed amount less that the final price for the underlying statistical or actual value of the binary option at expiration. Transactions are loaded in the clearing system and processed and all positions are liquidated.

FIELD OF THE INVENTION

The present invention relates to clearing positions for expired options,and more particularly, processing binary options as a non-tradeablecash-settled futures contract.

DESCRIPTION OF THE RELATED ART

Clearing processes are performed for derivative products, such asoptions or vanilla options, after an expiration date for the derivative.Derivative products include options on futures contracts, futurescontacts that are functions of other futures contracts, or otherfinancial instruments that have their price related to or derived froman underlying product. A clearing house may process or clear thederivative in a similar manner as for other derivatives, such as inexisting futures bookkeeping systems. The clearing house may break aderivative trade into a series of trades that appear to a member firms'bookkeeping systems as if they are standard monthly options on monthlycash-settled non-tradeable futures. That is, a series of trades are notfutures and futures-options, but may provide the appearance as such sothat they may be easily processed in existing bookkeeping systems.

Binary options, including binary range options, (also referred to asdigital options) are cash-settled options that pay a fixed amount if theoption ends up in-the-money. The payout amount does not depend on theamount by which the option ends up in-the-money. For a binary call, theoption pays if the final value of the statistic or actual value isgreater than or equal to a strike price for the option. For a binaryput, the option pays if the final value is less than the strike pricefor the option. A binary range option may have multiple strike prices,such as a lower and an upper strike price. The holder of the binaryrange option receives (and the seller pays) the fixed payoff amount ifthe final value of the statistic ends up greater than or equal to thelower strike, and less than the upper strike.

Because of the digital or binary nature of the option, existing clearingsystems may not be readily configured to process or clear a binary orbinary range option. To directly process these instruments, systemshandle (a) the different product characteristics—for example, the binaryrange options, with fixed payouts and two strike prices, (b) tradequantities which may be expressed as nominal amounts and very large, and(c) strike prices which may be negative. Therefore, the clearing housewill break up each trade in an actual auction instrument into a seriesof trades that appear to be ordinary options trades, in standard monthlyoptions on cash-settled non-tradeable futures, and should flow throughfirm bookkeeping systems with practically no modifications. Suchprocessing is time-consuming and requires cumbersome decomposition ofthe option.

Therefore, there exists a need in the art for systems and methods forconveniently clearing and processing binary options.

SUMMARY OF THE INVENTION

Systems and methods are described for processing binary options (alsoreferred to as digital options) in existing clearing systems, such asfutures clearing systems. The binary option is treated, or processed,similar to standard options on a non-tradeable cash-settled underlyingfutures contract. A hypothetical instrument, referred to as a bookinstrument is created to facilitate clearing of the binary option. Thebook instrument has an expiration date after the expiration of thebinary option, such as the day after the expiration of the binaryoption. For each binary option that expires in the money, a transactionis created for the book instrument future. The underlying book futurehas an assigned price that is one less than the final price for theunderlying statistical or actual value of the binary option atexpiration. Transactions are loaded in the clearing system and processedand all positions are liquidated. Options exercise and assignmentprocessing is performed in the clearing system as well as an associatedclearing firm bookkeeping system.

Exemplary Embodiments

FIG. 2 shows a flowchart for an exemplary method for clearing options.In the method, a binary option may be processed without cumbersomedecomposition into vanilla options.

In an embodiment, a clearing system is used to process an expired binaryoption. The binary option is processed as a standard option on anon-tradeable cash-settled underlying future, also referred to as a“book instrument.” (i.e. it is only to facilitate processing in clearingfirm bookkeeping systems.).

The book instrument is defined to have an expiration date after theexpiration of the corresponding binary option. For example, the bookinstrument may have an expiration date the day after the expiration ofthe corresponding binary option. In other embodiments, the bookinstrument and binary option may expire the same day with the binaryoption expiring before the book instrument.

The non-tradeable underlying future's maturity date may also be set toexpire the business date after the real option expiration date.

On or before the real expiration date, trading ceases for the binaryoption. Option expiration processing for the binary option is not run onthe normal expiration date for the binary option, since the date isdefined in the clearing system according to the book instrument as thenext business day.

On the expiration of the book instrument, such as the day after or intraday after the expiration of the binary option, exactly liquidatingtransfer transactions are created, loaded into the clearing system, andtransmitted to clearing firms for loading into their bookkeepingsystems, for each expired binary option position. For example, if aposition in an expiring option was 35 long by 17 short, then a selltrade for 35, and a buy trade for 17 are created. These transfertransactions are defined as liquidating, either trade by trade (if thatis how the clearing system operates for these products), or implicitlyby specifying an ending position (“position change specification”, orPCS) of zero by zero.

For each binary option position which has expired in-the-money,transactions are created for the underlying “book” instrument future, ata price with a value a fixed amount, such as one, less than the finalprice for the underlying statistic of the binary option:

-   i) For long call and short put positions, the book-instrument    futures transaction is created as a buy transaction; and-   ii) For short call and long put positions, the book-instrument    futures transaction is created as a sell transaction.

The liquidating transfer transactions for all the expired binary optionpositions, and the “book-instrument” futures transactions for thosewhich finished in-the-money, are loaded into the clearing system. Thisin turn causes messages to be transmitted to clearing firms to allow thetransactions to be loaded into clearing firm bookkeeping systems.

As clearing processing continues, no other transactions in these optionsare allowed to clear on that day; no special option instructions(exercise notices or option abandonments) are accepted, nor any positionadjustments or other transaction which could affect the ending optionposition. The net effect, together with the liquidating transfertransactions that have been posted to the expired option positions, isthat all such positions are liquidated.

Option exercise and assignment processing is run normally in both theclearing system and in clearing firm bookkeeping systems for the binaryoption positions, as if they were vanilla options, since the expirationdate in the clearing system has been set to a later date or time, suchas the next business day. However, since all of these option positionshave been liquidated, there are no positions to exercise or assign, evenfor the ones which finished in-the-money. Hence the fact that exerciseand assignment processing is run as if for vanilla options, creatingtransactions at the strike price, has no effect.

At the first clearing settlement cycle of that day, the special futurestransactions for the in-the-money options, created at a fixed price,such as one, less than the final value of the option's underlyingstatistic, are marked-to-market to that final value. This process, whichoccurs in both the clearing system and in clearing firm bookkeepingsystems, causes the binary payout cash flows to occur.

Money calculations for the book instruments, when calculating premiumfor trades in futures options in a bookkeeping system, the trade priceis multiplied by the contract value factor (the multiplier that convertsthe quoted price to its monetary value) and the trade quantity. In otherwords, for futures options, calculate the premium for a quantity of one,then round, then multiply by the trade quantity.
